Asyncawait is a language feature that allows you to write asynchronous code in a synchronous style. It simplifies working with asynchronous operations by providing a single point of agreement for how operations are handled.
Key benefits: Reduced code verbosity, improved readability, simplified error handling.
Let's look at a simple example:
await Promise.resolve(1).then(value => {
console.log(value);
});
Here we can see how to use async/await for better readability
Example:
async function fetchData() {
try {
const response = await fetch('https://api.example.com/data');
const data = response.json();
console.log(data);
} catch (error) {
console.error(error);
}
}
